Julia Roberts’ late half-sister left a suicide note citing her tortured relationship with the Oscar winner, a source close to the investigation told the Daily News Tuesday. It was definitely a suicide. She left a five-page suicide letter. The EMT found it," the source told The News.

Motes had been pet-sitting for a client who rented the home. She may have been dead for about 12 hours before her body was found, the source said.
“It looks like a pill overdose," the source said.
Motes, a Georgia native, was the daughter of Roberts' mother, Betty Lou, and stepfather, Michael Motes.

She had a falling out with Roberts, 46, after giving a tell-all interview last summer and accusing the “Pretty Woman” actress of blocking her access to their sick mother, the source said.
In the days leading up to Motes' death, she sounded emotionally unstable in posts on her Twitter account.
"So my 'sister' said that with all her friends & fans she doesn't need any more love. Just so you all know 'America's Sweetheart' is a B----!!'" she tweeted on Jan. 20, referring to Roberts' star turn in the 2001 rom-com “America's Sweethearts.”

“Do you want to be a fan of someone so cruel? She's not even that good of an actress. Happy you totally F---ed with me?" she added in a subsequent missive."(M)y own family has abandoned me," Motes tweeted Jan. 22.

The News confirmed the @Dabbs76 Twitter handle belonged to Motes before her death. The angry tweets were still visible late Monday but had disappeared by early Tuesday.Motes long struggled with being overweight and living in her vapid movie star sister's shadow.
